Missoula is a great airport. Desk and gate crews were very helpful and friendly

Other than delaying take off by an hour, the flight was smooth. Crew were kind and supportive, and made sure we were always considered as a priority.

Flight was on time. My pre-ordered meal came as expected.

Flight was delayed and we were left in the plane with planed turned off, took so long to get to destination and luggages were lost. Such a hectic travel

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

Flight was delayed, but not be a lot. Crew at the departure gate was friendly. Flight was filled with turbulence, enough to concern my husband. Snacks were delivered to rows in front of us but attendant stopped handing out snacks when she got to our row. Team was efficient but lackadaisical. Usually on board crews are more animated and friendly. No onboard entertainment and no seatback video screens for a six hour flight. Landing was a bit rough. We were told the wrong turnstile for luggage.

2 hour delay. Then some luggage was unloaded at 1baggage claim #7 then without notice the baggage claim was changed to #12. No one informed the passengers they were changing baggage claim turnstile. Several of us waited for 90 minutes after the 1st turnstile stopped and changed to other flights luggage.

Many gate changes in Seattle and mechanical problems on plane which resulted in a new gate change. Both flights, from Seattle to Detroit and Seattle to Eugene resulted in a lot of walking and tram taking.

No negatives. Crew was great, flight was on time and there were no crazy passengers. 🤩

I had ordered breakfast several days prior to the flight. 1) we did not rreceive our breakfast and crew knew nothing about it! We left TPA at 8 a.m. but drink cart did not appear until 10:30 a.m. and did not appear a second time either. Was unaware that Alaskan Air offers no music, flight aware, or movies.

Flight delayed two hours , missed connection flight then connection cancelled- horrible experience with hotel

Omg the disaster at the security was on another level! “Go to this end, sorry closed now, go to that end”. Ridiculous! This took over an hour! As far as the airline was concerned although I booked nearly a year ago I couldn’t get my bag tag - stand in another 15 minute line or my seat on Hawaiian Airlines- 5 more minutes! Then my TSA status was denied. Like what the heck! Makes a person not want to travel with this amount of incompetence

The Honolulu Hub needs 2 to 3 times the amount of things to do as well as shuttles that transport to/from gates and terminals. Arriving from OCONUS locations; transferring to CONUS locations its a miserable experience. Fetching and re-checking bags, then returning to a gate across the airport take longer than any other large airport. If youre confused by what I mean, the process goes like this: Disembark plane Walk a mile to the main terminal Walk half a mile to baggage claim Wait 40 minutes for baggage Walk a mile to re-check-in baggage Wait 20 minutes for checking in those bags Fo back through the wrong TSA line because the signage is poor Almost miss the connecting flight because your gate is across the airport.

The checking was disaster, the crew wasn't behave well. It took us two hours to check in, after that thr line at the TSA was long, we barely make the flight. Bad airline

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

Horrible food and crew. Crew were laughing and talking loud while people were trying to sleep

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Delayed and cancelled flights were hard and very stressful, both ways!
